-

pretty simple question. know how use fputcsv() insert row csv inserts @ bottom. there way use insert @ top of csv?

i need add header existing csv file.

any on great.

thanks!

fputcsv() inserts data @ file pointer, can rewind() pointer beginning of file.

rewind($handle); fputcsv($handle, $fields);

alternately, can open file pointer @ beginning:

$handle = fopen('yourfile.csv', 'r+'); fputcsv($handle, $fields);
